(This is almost certainly a "rerun," as I'm reasonably sure that a kid has said something like this in the past.)
We do a lot of sightreading in
lessons after Solo and Ensemble, and I always emphasize the importance
of checking the key signature--but sometimes after the fact...
KID: (misses key signature notes in the first measure of the piece)
ME: What's the first rule of sightreading?
KID: Don't mess up?
